They have been formulated from natural ingredients, (which presumably include KFC 's secret blend of 11 herbs and spices), and packaged in a stylish glass bottle "to appeal to young consumers' love of food and fashion".

"Simply apply and dry like regular nail polish and then lick - again and again and again to taste why the world's favourite chicken is Finger Lickin' Good," the company said in a press release seen by Racked .

The brand has even released a bizarre online music video to accompany the launch, which invites customers to vote for their favourite flavour to go into mass production.

While it's no joke - KFC really is making this stuff - it is not being mass produced.

The edible nail polish will only be available in Hong Kong, as part of a marketing campaign to promote its famous slogan.

Ogilvy & Mather, which worked with food technologists at McCormick to create the nail polishes, told AdWeek that the campaign was designed to be "intriguing and fun" and "increase excitement around the KFC brand in Hong Kong".
